A graphing calculator is recommended. When does the mass pass through the equilibrium position (the position when the system time? (Round your answer to two decimal places.) An elastic band is hung on a hook and a mass is hung on the lower end of the band. When the mass is pulled downward and then released, it vibrates vertically. The equation of motion is s(t) = 8 cos(t) + 4 sin(t), t 2 0, where s is measured in centimeters and t in seconds. (Take the positive direction to be downward. ) d) How far from its equilibrium position does the mass travel? (Round your answer to two d (a) Find the velocity and acceleration at time t. S = cm V (t ) = e) When is the speed greatest? (Use n, a positive integer.) a(t) = O 0.46 + nn O 0.46 + 2nn (b) Graph the velocity and acceleration functions. O 2.03 + nn O 2.03 + 2nn O O 2.49 + 3nut Submit
